CREATE KEYSPACE machine_tools WITH REPLICATION = { 'class': 'NetworkTopologyStrategy', 'dc-1': 1, 'dc-2': 3, 'dc-3': 3 };
Let us suppose if dc-1, dc-2 and dc-3 have 5 nodes each. During write operation one node is down in each datacenter. As per the replication factor in each datacenter, is it safe to say that I will have 6 copies of a row across three datacenters.
